WASHINGTON – The nation will bid goodbye to former President George H.W. Bush on Wednesday with a state funeral that will be attended by former presidents and foreign dignitaries present and past.

Bush, who died Friday at age 94 at his home in Houston, will be given a state sendoff with an invitation-only service at the Washington National Cathedral, just three miles from the White House, where he presided as the nation’s 41st president.

The ceremony, guided by tradition and protocol, will be the nation’s first presidential funeral since the cathedral hosted services for Gerald Ford in 2007.

National Day of Mourning

President Donald Trump has declared Wednesday a National Day of Mourning in honor of the 41st president, who managed the end of the Cold War and forged a global coalition to oust Iraqi forces from Kuwait.

Days of mourning are recognition given to a select few – in the U.S. usually commanders in chief – and involve memorial activities, flying of flags at half-staff and other remembrances.

The federal government will be closed, as will the New York Stock Exchange and Nasdaq. The U.S. Postal Service will not deliver regular mail, and all post office locations will be closed.

When do the services begin?

At 10 a.m. Eastern Standard Time, Bush’s flag-draped coffin will be removed from the rotunda of the U.S. Capitol, where he has been lying in state since Monday.

The coffin will be transported by hearse to the Washington National Cathedral, where the service will begin at 11 a.m. and run for about an hour and a half.

Often called the spiritual home of the nation, the cathedral was built by the Episcopal Church and is often the site of state funerals, presidential inaugural services and national prayer meetings.

The neo-Gothic structure, completed in 1990 after 83 years of construction, draws hundreds of visitors every year and has been the site of state funerals for former Presidents Dwight Eisenhower, Ronald Reagan and Gerald Ford.

Memorial services also were held at the cathedral for former presidents Warren G. Harding, William Howard Taft, Calvin Coolidge, Harry S. Truman and Richard Nixon as well as for other prominent Americans, including Washington Post publisher Katharine Graham and Arizona Sen. John McCain, who died in August.

The cathedral is also the final resting place of Woodrow Wilson, Helen Keller and Matthew Shepard, whose remains were interred in the cathedral crypt in October, two decades after his grisly death in an anti-gay hate crime shocked the nation.

Who’s attending?

A complete list of dignitaries attending has not been released, but Trump and first lady Melania Trump are expected to attend, along with all four living ex-presidents – Barack Obama, Bill Clinton, George W. Bush and Jimmy Carter.

German Chancellor Angela Merkel and Prince Charles of England are among the foreign dignitaries who will be on hand. Jordan’s King Abdullah II and his wife, Queen Rania, are scheduled to attend, along with Polish President Andrzej Duda, Australia’s Governor-General Sir Peter Cosgrove and former British prime minister Sir John Major.

George W. Bush, the nation’s 43rd president, will deliver the eulogy for his late father. Other speakers are expected to include former Canadian Prime Minister Brian Mulroney, former Wyoming Sen. Alan Simpson and Bush’s biographer, Jon Meacham.

Three of Bush's granddaughters also will have a role in the ceremony. Ashley and Lauren Bush, the daughters of Bush's son Neil, will do the first reading together. Jenna Bush, daughter of George W. Bush, will provide the second reading.

Trump, who has clashed with the Bush family, is not scheduled to speak.

What happens next?

After the service, Bush’s body will depart the cathedral at 12:30 p.m. for nearby Joint Base Andrews, where it will be flown back to Houston for additional services.

Bush will lie in repose at St. Martin’s Episcopal Church in Houston Wednesday night.
